To all whom it may concern:

Be 1t known that we, WALTER B. SWIN- DELL and CEoiL H. HGLLOWAY, citizens-of the United States, residing at Raleigh, in the county of Wake and State ofNorth Carolina, have invented a new and useful VWater- Heater, of which the followingis a specification. i

This invention relates to that class of Water heaters, in which water is forced in athin stream upwards, and then downwards, through spirally formed chambers located in the walls of circulating chambers subjected to heat by means of which water, heatedA to the desired temperature, is conducted toa boiler, or other receptacle. i

The invention has especial reference to that class of water heaters of this character, in which the Wateris circulated through the Walls of conical heating chambers, and has for its object to provide an improved Water heater of this character, by means of which a constant circulation of an extended surface of water over aneXtended heating'surface is created and maintained.

The'invention consists of a water heater, and in details thereof constructed andarranged as hereinafter set forth and claimed.

Referring to the drawing, igure 1 is a view in elevation, and partly in vertical section of a Water heater, constructed in accordance with this invention. Fig. 2 is a detail view of the upper end of the heater showing a slightly modified construction-of this ortion thereof, andFig. 3 is a similar view ut showing a further modification of one ofthe cap members.

In carrying out the invention a plurality of conical heating and Water circulating chambers are employed and as here shown consisting of two conical heating and circulating chambers l and 2, located adjacent to each other, and mounted in an oven 3, having ventilating openings 4. The water heater is mounted on an oil `stove 5, or other heating apparatus by means of suitable fastenings 6 and the heat is carried up through the bottom of the conical chambers 1 and 2, and out at their top. The heater may be provided with fastenings, to secure Yit` to a stove, or may rest on top of the stove Vwithout being fastenedto it. Each of the conical' heaters 1 and 2 is formed of two cones, located and spaced apart, one within the other, and open at the' top, and bottom, and fastened together and closed in any suitable manner, at their ends, the outer cone, forming the outer wall 7, and the innercone, forming the inner 'wall 8, of the conical heating chamber.

indentations or crirnps 9, which bear against the outer wall 7, and form a shallow spiral water channel 10 extending from top to bottom of the conical heater, between the walls 7 and 3.

- Above the `open tops of the conical heaters 1, is preferably mounted in any suitable manner a cone shaped cap 11, closed at the top, and formed of two cones 12 and 13, located one within the other and spaced apart, and closed at their lower edges. The inner cone 12, is formed with spiral indentations or channel 15 ,c extending from top to bottom of the cap 11v and connectin at its lower end by means of a pipe 16, Wit the up er end of the spiral channel 10, in conical c amber 1,

j and at its up er end with the upper end of spiral ohanne 10, in conical chamber 2, by means of a pipe 17.

It will be seen that the cap 11 is mounted on the` tops-of the conical chambers 1 and 2, slightly above their open Vupper ends by means of the pipes 16 and-17. Water is admitted at the lower end of spiral channel 10 by means of a short pipe 18, connected to the conical chamber 1, and having a threaded end 19, for attachment of a hose i e. Water is discharged from the lower endpof the spiral channel 1Q, in conical chamber 2 by means of a pipe 20, connected to the lower end of conical chamber 2, and a vertical pipe 21, connecting with said pipe 20, and extendin above the conical chambers 1 and 2, an terminating in a curved end 22, adapted to extend over the edge of the side of a bath tub. By having. the water outlet 22, elevated above the conical chambers 1 and 2, the lill- Iingof the conical chambers 1 and 2 at all times with water is assured. The pipes 18 and 20 are each provided with a `faucet 23 by means of which perfect drainage is secured. TWater is admitted throu h pipe 18 to the lower end of spiral channel 10, and traverses upwards through said spiral channel to the top Vof conical chamber 1, then through pipe 16, and spiral channel 15 to pi e 17 and down spiral channel 1() in conica chamber 2, to pipe 20, and from'pipe 20 up pipe 21, and out at outlet 22. The water descending from The inner wall 8 is formed with the spiral fr crimps 14, tforming a shallow spiral Water.

the top of the cap and down through the con ical chamber 2, secures' perfect drainage and circulation and the spiral water channel in conical chambers l and 2 provides both an extended heating surface and constant eirculation. The cap being slightly elevated above the open tops of the conical chambers 1 and 2 the 'neat passing through the latter is arrested by the cap, and utilized to heat it, the elevation and shape oi the cone giving sufiicient ventilation.

lin the modification shown in F ig. 2, two cone shaped caps 24, are employed, in lieu oi the single cone cap 1l, each oi said caps being constructed similarly to the cone cap il, the caps 24, being connected at their top by a pipe 25, and being slightly elevated above andmounted on the upper ends 26, oi conical heating and water circulating chambers by means oi connecting circulating pipes 27.

n the modification in Fig. 3, a portion oi a water circulating and cone shaped cap 2S is shown,A constructed similarly to the cone cap il and having in lieu oi the pipe connection 17,' a tubular connection 29, lormed oiz a strip of metal 30 soldered to the top of the cap.

Having described the invention we claim.
